Mound Septic Systems in Northwest Missouri
Been told your property needs a mound septic system? A difficult site doesn’t necessarily mean your building or replacement project has to stop.
Digger Dave installs advanced mound septic systems for new construction and replacement projects throughout Northwest Missouri and the Kansas City area. Send us your soil report or system design—or start with the property if you don’t have those yet.
What Is a Mound Septic System?
A mound septic system is an advanced onsite wastewater system that creates an elevated soil treatment and dispersal area above the existing ground surface.
Instead of placing the entire disposal field into the existing soil like a conventional system, carefully selected material and system components are used to create the treatment area required by the design.
This can provide another wastewater option for properties where the natural soil conditions don’t provide enough suitable treatment depth for a conventional system.
Why Would a Property Need a Mound System?
Mound systems are generally considered because of the property’s soil and site conditions—not because someone simply prefers a mound over a conventional septic system.
- Limited suitable soil depth
- Restrictive soil conditions
- High seasonal water conditions
- Difficult natural soil
- New construction on a challenging site
- Failed existing septic system
- Limited replacement options
- Need for additional treatment depth
- Property layout constraints
- Site conditions unsuitable for conventional laterals
If your soil report says a conventional system won’t work, a mound may be one of the advanced options worth considering.
How Does a Mound Septic System Work?
1. Wastewater Receives Initial Treatment
Wastewater first passes through the treatment portion of the septic system before being sent to the mound.
2. Wastewater Is Collected for Dosing
The system uses a dosing or pump component to deliver wastewater to the mound in controlled amounts.
3. Pressure Distribution Spreads the Flow
Wastewater is distributed across the designed absorption area rather than being allowed to concentrate in one location.
4. The Mound Provides Treatment & Dispersal
The designed mound and underlying soil work together to provide the treatment and dispersal area required for the system.
A Mound Is an Engineered System
A mound isn’t simply a pile of fill placed over a septic lateral field. The elevations, dimensions, materials, loading area and distribution system are important parts of how the system functions.
Mound systems require proper planning and design for the specific property.
Digger Dave can help coordinate the required design process and then install the system according to the approved plans.
Mound Septic Systems for New Construction
Finding difficult soil on a building lot can be frustrating, especially after you’ve already started planning the home.
But a property that doesn’t support a basic conventional system may still have advanced onsite wastewater options.
If your soil evaluation points toward a mound system, send Digger Dave the report. We can help move the wastewater project through design and toward installation.
Mound Systems for Septic Replacement
A mound may also be considered when an existing septic system has failed and the property doesn’t have suitable conditions for another conventional drain field.
Replacement projects can be more complicated because the existing home, well, driveway, outbuildings and old septic system already occupy parts of the property.
The goal is to find a replacement solution that works with the usable area and actual conditions of the property.
Mound Systems Use Pumps, Controls & Pressure Distribution
Mound systems typically rely on controlled dosing rather than simply allowing wastewater to flow into the disposal area whenever it leaves the septic tank.
- Septic and treatment components
- Dosing or pump tank
- Effluent pump
- Float controls
- High-water alarm
- Pressure distribution piping
- Designed absorption area
- Specified mound materials
Each component needs to match the approved design so the entire system operates as intended.
What Will a Mound Look Like in My Yard?
A mound system creates a raised area above the surrounding grade. Its final size and shape depend on the system design and property conditions.
Proper final grading matters. The finished area should be shaped to protect the system, manage surface water and blend into the property as reasonably as the design allows.
Because a mound remains part of the wastewater treatment system, it should also be protected from vehicle traffic, excavation and other activities that could damage it.
Already Have a Mound System Design?
Send it over.
If your soil evaluation and mound design are already complete, send Digger Dave the plans, property address and any available permit information.
We’ll review the project from the installation side and determine what is needed to get it priced and built.
Don’t Have the Design Yet?
That’s okay. You don’t have to coordinate the entire process before calling an installer.
If you’ve been told the property may require a mound—or you simply know the soil isn’t suitable for a conventional system—start with Digger Dave.
Send us the property address and any soil or septic information you already have. We’ll help get the project moving through the appropriate next steps.
Mound Septic Installation Throughout Northwest Missouri
Digger Dave installs mound septic systems throughout Northwest Missouri and the Kansas City area, including the Kansas City Northland and communities throughout our broader service area.
If you have a soil report or septic design calling for a mound system, send it over. If you’re still trying to figure out what the property needs, send us the address and we’ll help get the process started.
Mound Septic System FAQs
Why would I need a mound septic system?
A mound may be considered when the natural soil doesn’t provide the conditions needed for a conventional system. The mound creates an engineered treatment and dispersal area based on the property’s conditions.
Does a mound septic system require a pump?
Mound systems typically use a pump and controlled dosing to distribute wastewater through the designed absorption area.
Does a mound septic system require electricity?
Systems using pumps, controls and alarms require electrical power for those components.
Can you drive over a septic mound?
The mound and absorption area should be protected from vehicle traffic, heavy equipment and activities that could compact or damage the system.
Can a mound be used for a replacement septic system?
Potentially. A mound may be one replacement option when the property doesn’t have suitable conditions for another conventional field. The appropriate system depends on the specific site and design requirements.
How big will the mound be?
The dimensions depend on wastewater flow, soil and site conditions, design criteria and the specific system configuration. The approved design determines the actual footprint.
Can Digger Dave install an engineered mound system?
Yes. If you already have an engineered design, send us the plans and property information. If you’re earlier in the process, contact us and we’ll help get the septic project moving toward installation.
Been Told You Need a Mound Septic System?
Send Digger Dave your soil report, septic design or property address. Whether you’re ready for installation or still figuring out the next step, we’ll help get the project moving.
